In some of my talks, I sometimes refer to DKIM as "DomainKeys Version 2". This gets people thinking in the right frame of mind as to their relationship. Tony Hansen [EMAIL PROTECTED] Murray S. Kucherawy wrote: > Sorry, I wasn't done yet. > > The main reason I wanted to share th

I was at Michael Barrett's (PayPal CISO) talk yesterday morning. He said that the early gains they have made have been with DomainKeys, but said quite clearly that "the future is definitely with DKIM" (or words to that effect). He said that Yahoo! had blocked 50 million messages allegedly from

One more question: what is Yahoo! looking at to determine "allegedly from paypal.com"? My guess is some subset of the From: header field, the Sender: header field, the Reply-To: header field, the 821.MailFrom return path, the Resent-From: header field, the Resent-Sender: header field, or do the
